This is an old revision of the document!
I've tested this on Ubuntu 7.10 Gutsy Gibbon - x86 architecture - 32 Bit, but I don't see why it shouldn't work on other OS's.
You need a Internet Connection with your LAN Cabel.
Open a Terminal and type…
sudo apt-get install build-essential sudo apt-get install libssl-dev
wget http://dl.aircrack-ng.org/drivers/ipwraw-ng-2.3.4-04022008.tar.bz2 tar -xjf ipwraw-ng* cd ipwraw-ng make sudo make install sudo make install_ucode echo "blacklist ipwraw" | sudo tee /etc/modprobe.d/ipwraw sudo depmod -ae
The device created will automatically be in monitor mode.
sudo modprobe -r ipw3945 sudo modprobe ipwraw
Configure your Wireless Card
You can use iwconfig to set the channel and rate and transfare power. The device name must not “eth1” it can be “wifi0” or what ever. You can see this with “iwconfig”.
iwconfig eth1 channel 11 (on which you want to sniff) iwconfig eth1 rate 1M (min=1M and max=54M) iwconfig eth1 txpower 16 (min=-12 and max=16)
And when you're done,
sudo modprobe -r ipwraw sudo modprobe ipw3945

Also consider using the Wifi-Way live CD instead.
